In carrying out the present invention the mold board 1 which is of the ordinaryshape is constructed out of sheet .metal being of Fig. 8 is a similar view of the plow uniform'gage or thickness throughout and for the urpose. of this invention the forward edge of t e In 1d hoard cut away, as shown at 2 to provi e. an acute angled notch 3 adapted to receive the correspondingly shaped upper extremity 4 of the plow point 5, the rear edge 60f which fits against the cut away edge 2 of the front of the mold board as shown in Figs. 4 and 5, whereby an interlocked engagement is obtained between the plow point and the mold board.

v The share'7 which is illustrated in detail in Fig. 5 is in the form of a straight har adapted to be rolled out in. a mill and given the cross sectional shape shown. In other words, the share comprises a cutting edge .8 which is p referahly rounded oli toward the front end as shown at 9, the opposite edge being rahbeted throughout its entire lengthv as shown at 10, the depth of said rahbet being just sufficient to'i'eceive the bottom edge of the mold board, as shown in Figs. 1 and 2 whereby the upper active surface of the share and mold board are brought flush relatively to each other so as to form a practical cmitinuous surface. The share 7 is filltl'lCI' PTOVitlGd with a plurality cfsockets or holes 11 which are adapt ed to receive studs or correspondingly shaped projections 12 on a clamp l3 Wl1lCl1yltS shown in l ig. 6, is eoncavo convex. in cross section, the concave sidathe'reoi lacing presented to ward the under sid'ejof the share and mold board. if 'llhdclanlpilii :is provided with holes 14 and the mold; hoard 1 is provided with correspending holes late receive removable bolts 16 whereby theclamp is held in place and adapted to he removed. One edge of the clamp hears against thc share while the other edge thereof-hears against the mold board. The share 7-is milled in long bars which are subsequently cut the proper length and hardened thus making a cheap and eiiect we share. The land side or bar 117 may be of any suitable lengthand has-its forward portion cut away atzthe'top as shown at 18 to correspond toths shape of. theunder side.

of the mold board and is also provided with an inwardly projecting. flange 19 which extends und board and-is secured thereto h, theirsuitable fasteners 20' passing through e mold board and said flange. A portionofthe flange 19 is slightly raised as shown at 2liand is provided with a hole 22 which registers with a hole 23 in the plowpoint the same being adapted to receive a suitable fastener. 2-l preferably" a bolt, whereby the low point is detaohahly connected to the .ange of theland side or bar l 7.

In the preferred embodiment of the inventiorn the fastener 24 consists of a long bolt, one endv of which is bent to extend through the holes 22 and 23, the'remainder of said holt extending straight hack. and passing through. a notch in cross bar 25 the opposite ends of-which-are secured to the mold board and land side or bar as clearly shown in Fig. 3, a nut 26 being laced on the end of the bolt 24 and screws up tightly against the 'bi'ace'25, as. shown.

. The land side or'bar 17 is provided with I down thus dis being the plate bottom ortion of the hee piece at an angle to the wt tom. edge of the land side, which has the of fect of uplifting the rear portion of the plow and giving-the seine a greater. downward pitch so as to causefthe plow-to penetrate deeply into .the. ground. The forward edge of the bottom portion of the heel piece is set registers with the opening in the plow point, p

into a notch in the bottom edge of the land bar as shown at 30.

By means of the construction above described, the share is connected to the mold board without in any way impairing the strength of the mold board thus adapting the mold to be 'formed out of a suitable blank of sheet metal of the proper gage or thickplow point having an opening therein, a land side having an inwardly projecting flange secured to the underside of the mold board, a lateral portion '21 of the flange beingraised and provided with an opening therein which a. plow share having a beveled cutting edge and a continuous longitudinally rabbeted upper portion to receive the lower edge of the mold board, a concavo-convex clamp having its concave portion contacting wit 1 the inner faces of the plow share and mold board and secured thereto, an angular brace having a horizontal Wardly extended vertical portion provided with a notch, the horizontal portion of the brace being secured to the mold board, a

bolt having a bent forward end which is inserted through the registering openings of the plow point and land side, the bolt being rearwardly extended and having its rear end connected to said notch, and ,meanson said connected rear end contacting with said vertical portion of the brace so as to permit of fastening the bent end of the rod in the registering openings of the plow point and mold board, and said landside having an adjustable rabbeted heel piece, substantially as specified, i

In testimony whereof I aflix my signature in presence of two witnesses.
